2023-11-27target/arm: Handle overflow in calculation of next timer tickPeter Maydell
In commit edac4d8a168 back in 2015 when we added support for the virtual timer offset CNTVOFF_EL2, we didn't correctly update the timer-recalculation code that figures out when the timer interrupt is next going to change state. We got it wrong in two ways: * for the 0->1 transition, we didn't notice that gt->cval + offset can overflow a uint64_t * for the 1->0 transition, we didn't notice that the transition might now happen before the count rolls over, if offset > count In the former case, we end up trying to set the next interrupt for a time in the past, which results in QEMU hanging as the timer fires continuously. In the latter case, we would fail to update the interrupt status when we are supposed to. Fix the calculations in both cases. The test case is Alex Bennée's from the bug report, and tests the 0->1 transition overflow case.

2023-11-27target/arm: Set IL bit for pauth, SVE access, BTI trap syndromesPeter Maydell
The syndrome register value always has an IL field at bit 25, which is 0 for a trap on a 16 bit instruction, and 1 for a trap on a 32 bit instruction (or for exceptions which aren't traps on a known instruction, like PC alignment faults). This means that our syn_*() functions should always either take an is_16bit argument to determine whether to set the IL bit, or else unconditionally set it. We missed setting the IL bit for the syndrome for three kinds of trap: * an SVE access exception * a pointer authentication check failure * a BTI (branch target identification) check failure All of these traps are AArch64 only, and so the instruction causing the trap is always 64 bit. This means we can unconditionally set the IL bit in the syn_*() function.

Worse, although .NOTPARALLEL is specified, it does not work for patterns, and run make in parallel, which can break things. Add a new rule "build", and let it call make. The pattern rule only needs to specify "build" as its prerequisite and have a no-op recipe so that it does more than canceling built-in implicit rules.

2023-11-24coverity: physmem: use simple assertions instead of modellingVladimir Sementsov-Ogievskiy
Unfortunately Coverity doesn't follow the logic aroung "len" and "l" variables in stacks finishing with flatview_{read,write}_continue() and generate a lot of OVERRUN false-positives. When small buffer (2 or 4 bytes) is passed to mem read/write path, Coverity assumes the worst case of sz=8 in stn_he_p()/ldn_he_p() (defined in include/qemu/bswap.h), and reports buffer overrun. To silence these false-positives we have model functions, which hide real logic from Coverity. However, it turned out that these new two assertions are enough to quiet Coverity. Assertions are better than hiding the logic, so let's drop the modelling and move to assertions for memory r/w call stacks. After patch, the sequence cov-make-library --output-file /tmp/master.xmldb \ scripts/coverity-scan/model.c cov-build --dir ~/covtmp/master make -j9 cov-analyze --user-model-file /tmp/master.xmldb \ --dir ~/covtmp/master --all --strip-path "$(pwd) cov-format-errors --dir ~/covtmp/master \ --html-output ~/covtmp/master_html_report Generate for me the same big set of CIDs excepept for 6 disappeared (so it becomes even better).

2023-11-23tests/tcg: finesse the registers check for "hidden" regsAlex Bennée
The reason the ppc64 and s390x test where failing was because gdb hides them although they are still accessible via regnum. We can re-arrange the test a little bit and include these two arches in our test. We also need to be a bit more careful handling remote-registers as the format isn't easily parsed with pure white space separation. Once we fold types like "long long" and "long double" into a single word we can now assert all registers are either listed or elided.

2023-11-22target/riscv/cpu_helper.c: Fix mxr bit behaviorIvan Klokov
According to RISCV Specification sect 9.5 on two stage translation when V=1 the vsstatus(mstatus in QEMU's terms) field MXR, which makes execute-only pages readable, only overrides VS-stage page protection. Setting MXR at HS-level(mstatus_hs), however, overrides both VS-stage and G-stage execute-only permissions. The hypervisor extension changes the behavior of MXR\MPV\MPRV bits. Due to RISCV Specification sect. 9.4.1 when MPRV=1, explicit memory accesses are translated and protected, and endianness is applied, as though the current virtualization mode were set to MPV and the current nominal privilege mode were set to MPP. vsstatus.MXR makes readable those pages marked executable at the VS translation stage.

2023-11-22riscv: Fix SiFive E CLINT clock frequencyRomán Cárdenas
If you check the manual of SiFive E310 (https://cdn.sparkfun.com/assets/7/f/0/2/7/fe310-g002-manual-v19p05.pdf), you can see in Figure 1 that the CLINT is connected to the real time clock, which also feeds the AON peripheral (they share the same clock). In page 43, the docs also say that the timer registers of the CLINT count ticks from the rtcclk. I am currently playing with bare metal applications both in QEMU and a physical SiFive E310 board and I confirm that the CLINT clock in the physical board runs at 32.768 kHz. In QEMU, the same app produces a completely different outcome, as sometimes a new CLINT interrupt is triggered before finishing other tasks.

However, QEMU has been implemented them long before it and thus they are forced to be on during the cpu initialization to ensure compatibility (see riscv_cpu_init). riscv_cpu_disable_priv_spec_isa_exts was not updated when the above behavior was introduced, resulting in these extensions to be disabled after all.

2023-11-22hw/riscv/virt.c: do create_fdt() earlier, add finalize_fdt()Daniel Henrique Barboza
Commit 49554856f0 fixed a problem, where TPM devices were not appearing in the FDT, by delaying the FDT creation up until virt_machine_done(). This create a side effect (see gitlab #1925) - devices that need access to the '/chosen' FDT node during realize() stopped working because, at that point, we don't have a FDT. This happens because our FDT creation is monolithic, but it doesn't need to be. We can add the needed FDT components for realize() time and, at the same time, do another FDT round where we account for dynamic sysbus devices. In other words, the problem fixed by 49554856f0 could also be fixed by postponing only create_fdt_sockets() and its dependencies, leaving everything else from create_fdt() to be done during init(). Split the FDT creation in two parts: - create_fdt(), now moved back to virt_machine_init(), will create FDT nodes that doesn't depend on additional (dynamic) devices from the sysbus; - a new finalize_fdt() step is added, where create_fdt_sockets() and friends is executed, accounting for the dynamic sysbus devices that were added during realize(). This will make both use cases happy: TPM devices are still working as intended, and devices such as 'guest-loader' have a FDT to work on during realize().

Allow the VIA IDE controller to switch between both legacy and native modes by calling pci_ide_update_mode() to reconfigure the device whenever PCI_CLASS_PROG is updated. This patch moves the initial setting of PCI_CLASS_PROG from via_ide_realize() to via_ide_reset(), and removes the direct setting of PCI_INTERRUPT_PIN during PCI bus reset since this is now managed by pci_ide_update_mode(). This ensures that the device configuration is always consistent with respect to the currently selected mode.

This function reads the value of the PCI_CLASS_PROG register for PCI IDE controllers and configures the PCI BARs and/or IDE ioports accordingly. In the case where we switch to legacy mode, the PCI BARs are set to return zero (as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing. Conversely when we switch to native mode, the legacy IDE ioports are disabled and the PCI interrupt pin set to indicate native IRQ routing. The contents of the PCI BARs are unspecified, but this is not an issue since if a PCI IDE controller has been switched to native mode then its BARs will need to be programmed.

core These definitions are present in ioport.c which is currently only available when CONFIG_IDE_ISA is enabled. Move them to the IDE core so that they can be made available to PCI IDE controllers that support switching to legacy mode.

2023-11-21iotests: Test two stream jobs in a single iothreadKevin Wolf
This tests two parallel stream jobs that will complete around the same time and run on two different disks in the same iothreads. It is loosely based on the bug report at https://issues.redhat.com/browse/RHEL-1761. For me, this test hangs reliably with the originally reported bug in blk_remove_bs(). After fixing it, it intermittently hangs for the bugs fixed after it, missing AioContext unlocking in bdrv_graph_wrunlock() and in stream_prepare(). The deadlocks seem to happen more frequently when the test directory is on tmpfs.
